it's getting off topic, but i really dont get it why you cannot go via 
the standard LEDS framework, and why you have to hook into the x86 idle 
notifiers. (which we are hoping to get rid of)

RAS does not need that precise accounting. It just needs a heartbeat 
timer that tells it how to do the pretty lights and to report whether 
the CPU is still alive. Something that seems to be fully within the 
scope of LEDS. What am i missing?
